Wireless battery charger via carrier frequency signal

Abstract

Apparatus and methods to wirelessly charge batteries within a radius of a power source. A power transmitter generates a power signal of specific configuration which is received by the power charger. The power charger harvests the received power signal and stores the energy contained within for the purpose of charging target battery or batteries. The typical uses of this invention are but not limited to the home, car, office, and work place. Anywhere where rechargeable batteries are used in a device where they need to be placed or physically removed from the device for recharge by conventional wired chargers, this invention provides method to prolong battery life in such a way to extend the time between a physical wired recharge or eliminate such events all together.

Description

FIELD OF THE INVENTION [0001] The present invention relates to charging batteries and in particular, to transmitting a carrier signal from a power source to a receiver which store the energy. BACKGROUND OF THE INVENTION [0002] Many commonly used items require batteries. The two most common battery types are disposable and rechargeable. If a device uses a rechargeable battery, the device must be physically plugged into a charging receptor for recharge. Depending on the intended use of the device, it is often desirable to use the device with rechargeable batteries; however, it is not always convenient to worry about plugging in the device for recharging. [0003] Nikola Tesla described the effects of transmitting energy through natural media, the basis for all radio transmissions. The present invention uses the principals set forth in his work for the specific purpose of harvesting the power of a transmitted power signal to charge batteries. [0004] It is therefore an object of this inve...

Benefits of technology

[0005] In accordance with the present invention, there is provided a process and electrical circuitry to wirelessly transmit a power signal. The power signal is received by a receiver that stores energy for the purpose of charging one or more batteries. The transmitted power signal is configured to reduce interference with other wireless signals in the vicinity of the power transmitter and receiver.
